A Dangerous Worm.
IMPORTANT TO FARMERS
A communication has been l-eceived by the Minister of Mines and Agriculture, from Mr W. Easson, of Pretty Gully, near Glen limes, together with specimens of potatoes, carrots, parsnip and peach tree roots, showing the ravages caused by what has since been ascertained to be a worms similar, to that which has for some years past devastated the beet growing lands m Germany. The identification has been made by Dr Cobb, after a month's patient investigation, and the Minister has consequently lost no time m warning agriculturists to be on their guard and take steps to prevent the increase of this terrible destroyer of root crops. It is named by Dr Cobb 'lpten)hus arenarious; but th« same worm is designated Anguillula arenaria by Neal m the United States, where thousands of miles of country have been rendered useless for root crops and peach tree cultivation. The worm m question is about l-60th of an inch m length, and by means of its spear like head and suoking apparatus it enters the tender tissues of young roots, producing" galls which cause these rootlets to, appear like rotted threads. The, following experiment was successfully carried out m a piece of infested ground. A portion was sown w,ith beet, and the worn^s promptly made their attack, In a month's tim,e, jusb befqre the eggs; laid by these worms were hatched, the crop, was ploughed up,, destroying; the wqrms and eggs, and. on the experiment being repeated three tjn\e« the ground was, (completely cleared of the pest. In order tq sJiow- the prevalance of the, worm it may be mentioned that no less than 13,000 were found m a potato 2|oz m weight.
